Abstract

A cap device for bottles, which is capable of mixing an additive contained therein with a material contained in a bottle to prepare a mixture in accordance with a simple rotating action of the cap device relative to the bottle, and which allows the mixture to be quickly discharged from the container. In the cap device of the invention, having a valve member seated in a neck of a bottle; a cap body tightened to an externally threaded mouth of a bottle and opened or closed at a lower end of a funnel part thereof by the valve member; and a cap cover acting as an additive containing part and assembled with the cap body to define a cavity therein to contain an additive in the cavity, the neck of the bottle is tapered downward on an inner surface thereof; the valve member is provided with a valve part at a center thereof to open or close the lower end of the funnel part of the cap body, with a plurality of radial ribs extending outward from an external surface of the valve part while defining a plurality of additive discharging holes between the radial ribs, the valve member also having a ring to surround outside ends of the radial rings, and a wedge-tipped shank vertically extending upward from a center of the valve part; a tapered surface is formed along an outer surface of the ring to correspond to the tapered inner surface of the neck of the bottle; and a vent hole is formed at a predetermined position of an upper end of the funnel part of the cap body.

2. The cap device as described in claim 1 wherein said shank extending from said valve part has a wedge-shaped tip.

3. The cap device as described in claim 2 wherein said valve member has a plurality of radial ribs extending outward from an external surface of the valve part while defining a plurality of additive discharging holes between the radial ribs;

said valve member also having a ring to surround outside ends of the radial ribs; and

,

said ring having an outer surface which is tapered to correspond to the tapered inner surface of the neck of the bottle.

4. The cap device as described in claim 1 further comprising a vent hole formed at a predetermined position of an upper end of the funnel part of the cap body.

5. The cap device as described in claim 4 further comprising a vent tube extending from said cavity and into said vent hole.

6. The cap device for bottles according to claim 1, further comprising:

a protective cover to receive the cap cover therein while holding the cap cover by means of upper locking means, and removably fitted over an upper part of the bottle by means of lower locking means.

7. The cap device for bottles according to claim 6, wherein the upper locking means comprises a locking flange formed along an outer edge of a top wall of the cap cover and a locking groove formed around a comer of a depression provided at a lower surface of a top wall of the protective cover, such that the locking flange of the cap cover removably engages with the locking groove of the protective cover;

and,

wherein the lower locking means comprises a locking flange formed around an inner surface of a lower edge of the protective cover and a locking groove formed around the upper part of the bottle, such that the locking flange of the protective cover is removably fitted over the locking groove of the bottle.

8. The cap device for bottles according to claim 1, wherein the bottle comprises:

a first container part externally formed at a bottom of the bottle, and having an open lower end, with external threads formed at the lower end of the first container part;

a first chemical contained in the first container part;

a breakable sheet provided at the open lower end of the first container pail to close the lower end of the container part;

a second container part having an open upper end, and externally engaging with the external threads of the first container part, the second container part containing therein a second chemical which produces a cooling mixture to absorb heat from surroundings to cool the surroundings when the second chemical is mixed with the first chemical;

a breaking edge provided at an inner surface of the second container part so as to break the breakable sheet and to open the lower end of the first container part, when the second container part is rotated to move upward relative to the first container part; and

a skirt extending downward from a sidewall of a lower portion of the bottle so as surround the first and second container parts.

9. A bottle having a cap device for separate storage of an additive therein and for release of said additive into said bottle as said cap device is being removed from said bottle, said bottle having a neck and an externally threaded mouth;

said cap device comprising;

a cap body twistably attaching to said externally threaded mouth of said bottle;

a funnel part integrated with said cap body, said funnel part having an opening at a lower end thereof;
